R/ mad ATTORNEY INV NTZ Patented June 23, 1931 S A S PATENT- oFF cE wmm E. BRo AivnEE, or Moi rcmim, NEW JERSEY, ASSIGNOR 15o AMERICAN MA- GHINE & o nE COMPANY, A conronnrron on NEW JERSEY Ho'r ,AND coLn 'cIeAEErrE non sEALEn Application filed April 30,

Thisinvention relates to hot and cold cigarette rod sealers forcontinuous rod cigarette machines, such as are used for the purpose of sealing the freshly pasted seam 1' of the cigarette rod before it enters the cut- 910 slightlymoist on emerging from the sealer.

This moisture on the-paper of the cigarette rod causes trouble in the operation of the machine, especially at the point at which the cigarette rod :enters the mouth-piece and ledger tube of thehutofi'.

To overcome this trouble, which increases with the speed ofthe machine, the present improved sealer. is provided witha heating unit which operates on the seam and squeezes out and carries off the surplus paste and is also provided with one or'more cold dryin bars which cool oifthe paste'and avoi sweating of the cigarette rod inithe cutoff mechanism. In order to'set the paste in. the seam and to dry thesurplusxtaken off, the heating unit is made in the form of a rotary disk which turns with the advancing cigarette rod and heats the latter at the point of, tangency only. The subsequent long contact of the cigarette rod with'the cold-:sealing'bars'jcause's the condensation of all moisture, so that the rod is entirely dry when leaving the sealing unit and a smooth running of the machine is secured.

The main object of the present invention is, therefore, the production of a sealer for continuous rod cigarette machines which avoids the disadvantages of prior constructions pointed out above, by the provision of cooling means together with heat applying means for operating on the seam of the cigarette rod. With these and other objects in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifi- 1930. serial No. 4455 7.

which like characters of reference indicate In the best constructions contemplatedythe heat applying means includes a heated rotat able disk and the pressure applying and cooling means includes 'a plurality of cooling bars. In the best constructions contemplated, also', these means aresupported-in a frame moveable in and out of operative po' sition. I 1 Referring to the drawings,-the entire sealing unit is mounted on a swingable frame or arm'5 mounted on a pivot 6 which is supported by the sealer bracket 7 fastened to the framev of the cigarette machine. The

- arm 5 carries a bracket 8 supporting a heat insulating-disk 9,- of asbestos or any other suitable material, towhich is fastened'the heat distributing disk. 10 having imbedded in it the electric heating unit 11. The arm 5 is provided with ballbearing's 12-su'pport- 7 ing the horizontalflsealing disk shaft 13 which has an integral flange l supporting aheat insulatingv disk 15 'COIWhioh'iS fastened the sealing disk 16, which is spaced from thefheat distributing disk '10 toreceive heatby radiation therefrom. Sealing disk 16 v.is frictionally driven from the continuously moving cigarette rod C. A hand wheel-17 is. provided onjthe'shaft 13through which the sealingdisk- 16 may be turned by handif desired. i I l Y The heating unit 'llreceive's electric current through wires 18 :passing through conn'ection box 19'mounted on arm 5. The latterfurthermore carries the heat insulating plate 20 on whichis mountedwthe first cooling ,bar 21 which'is slotted at its forward end to clear thesealing disk 16 so as to'peris likewise mounted on arm 5, but without heat insulation, in order that it may" distribute the heat received by it from-the seam to the frame, thereby maintaining a temperature lower than that of the seam..

In order to regulate the friction of the sealing disk 16 and of the cooling bars 21 and 22 on the continuously travelling cigarett'e' rod C,-arm 5 is provided with an ad justing screw 23 resting'on lug 24= of the sealer bracket 7, which enables the operator to raise or lower the sealing unit. The adjusting screw 23 has a lock-spring 25. For conveniently performing a complete backswing of the sealer, when the machine is stopped for any reason with a cigarette rod in place, a handle '26 is provided which is fastened to arm- 5.

In view of the foregoing, a detailed description of the operation of the machine is deemed to be unnecessary, and it is therefore Omittedin the interest of brevity.

What is claimed is:'.

1. The combination with means for applying heat to the freshly pasted traveling seam of a cigarette rod, of mechanism for immediately thereafter applying pressure and cooling said seam, whereby sweating of the cigarette rod is avoided. ,v v V 2. The combination withmeans for apply ing heat to the freshly pasted traveling seam of a cigarette rod, of'mechanism for immediately thereafter applying pressure and cooling said-seam, whereby sweating of the cigarette rod is avoided, said means including a heated wheel contacting saidseam. V

8. The combination with means for applying, heat to the freshly pasted traveling seam ofa cigarette rod, of mechanism for imme diately thereafter applying pressure and cooling said seam, whereby sweatingof the cigaretterod is avoided,-said means including a heating wheel, contacting with and rotated by saidvseam. V

4. The combination with means for applying heat to the freshly pasted traveling seam of a cigarette rod,yof mechanism for immedately thereafter applying pressure and cooling said 'seam, whereby sweating of the cigarette rod isavoided, 'saidmeans including a wheel contacting withisaid seam, and an electrically, heated member out. of contact with-butheating said wheel-by, radiation. I 5. The combination'withmeans for apply ing heat to the freshly. pasted traveling seam of acigarette rod,- of mechanism for imme-' diately thereafter applying 'pressure and cooling said seam, whereby sweating of the cigarette rod is avoided, said mechanism including an unheated bar extending along said seam behind said heat applying means. 6. The combination with a frame movable in andout of operative position, of means supported in said frame for heating the pasted seam of a traveling cigarette rod, and

mechanism supported by the frame for there- 7 said frame and contacting with the seam in the operative position, of the frame and adapted to be rotated by. the cigarette rod.

8. The combination with aframe movable in and out of operative position,of means supported in said frame forheating the pasted seam ofatraveling cigarette rod,- and mechanism supported by the frame for there after cooling the seam, whereby sweat-ing of the, ciga'retterod is'javoided," said means including a heated disk and .a heating member therefor. v

, 9. The combination with a frame movable in and out, of operativeposition, of means supported in said frame for heating the pasted seam of atraveling cigarette rod, andmechanism supported by the frame for thereafter cooling the seam, whereby sweating of the-cigarette rod is avoided, said mechanism including an insulated cooling bar disposed adjacent .tothe. heating means and adapted to engage the seam and a non-insulated cooling bar remote from said heating means and adaptedto engage the seam;

In testimony whereof, I have signed my name to thisspecification. V
